Product Description

General

 

Outdoor vacuum disconnecting load switch (short for load switch) is outdoor HV switchgear with three-phase AC 50Hz,rated voltage12/40.5kV. It is used for switching on/off load current in city or country distribution systems or breaking transfer currentof fuses. Matching with motor mechanism and controller, it can be used as a section switch or sectionalize.

Service environment

 
  • Ambient temperature :+40ºC~-40ºC, daily temperature difference :25K;

  • Altitude: no more than 2000 meters;

  • Wind pressure does not exceed 700Pa(equivalent to 34m/s wind speed);

  • Amplitude: no frequent violent movement, seismic intensity does not exceed 8 degrees.

  • Air pollution level 3;

  • Condensation may occur during periods of high humidity when the temperature drops;

  • Not applicable to places with fire, explosion, chemical corrosion and violent vibration.

Key Feature

 
  • Using vacuum arc extinguishing chamber, no explosive danger.

  • The isolation knife is connected with the three-phase vacuum interrupter, and there is an obvious isolation fracture when the brake is opened.

  • Can pull the brake with load, safe and reliable, long electric life.

  • All parts of the body are made of stainless steel, and the bottom frame is made of stainless steel or carbon steel with hot dip galvanizing and ultraviolet protection coating to ensure the normal operation of the body in the outdoor environment.

  • The installation mode is double rod type, electric operation is the main, and manual or remote control operation can also be used.

  • Widely used in rural urban network, railway and other configuration power line transformation.
